DESCRIPTION The SK5100/SK5101 is a keyboard encoder with a user-programmable keyboard matrix and an interface that can be configured to a USB or PS/2 interface. The IC can be programmed to any keyboard with four matrix tables for FN and NUMLOCK cases, so the IC is the best choice for custom keyboard solution but with an off-the-shelf IC. SK5101 is the pin-to-pin compatible low cost version of SK5100. The only differences are operation temperature range and pin36. The SK5100/SK5101 scans and encodes an 8-row by 20-column matrix. The encoder gets matrix information from on-chip flash matrix table. Sprintek provides Windows® application FlexMatrix Editor and Programmer software to edit, download and upload the matrix table. The SK5100/SK5101 provides an external PS/2 port that supports hot plug and hot swap of PS/2 mouse and keyboard devices. If the IC is configured to PS/2 interface, then the IC external PS/2 port supports only keyboards. If the IC is configured to USB interface, then the IC external PS/2 port supports keyboards, mice including wheel mice.

PIN ASSIGNMENTS

FUNCTION BLOCK DESCRIPTION

The SK5100/SK5101 consists functionally of several major sections (see the block diagram on the previous page). These include the keyboard interface, the oscillator circuit, the 16-bit timer, programming interface, external PS/2 port, backlight control circuit, GPO&SCO control, flash data block and the USB/ PS/2 interface. All sections communicate with each other and operate concurrently.

Keyboard Interface

The SK5100/SK5101 scans a keyboard organized as an 8 row by 20 column matrix for a maximum of 160 keys. Smaller size matrixes can be accommodated by leaving unused pins open. The IC provides internal pull-ups for the row input pins. When active, the encoder selects each column line (C0-C19); for each column selected, it reads the row data lines (R0-R7). A key closure is detected as a zero in the corresponding position of the matrix.

Each key found pressed is debounced for a period of 28 ms. Once the key is verified, the corresponding key code(s) are loaded into the transmit buffer.

In any scanned contact switch matrix, whenever three keys defining a rectangle on the switch matrix are pressed at the same time, a fourth key positioned on the fourth corner of the rectangle is sensed as being pressed. This is known as the “ghost” or “phantom” key problem.

Although the problem cannot be totally eliminated without using external hardware, there are methods to neutralize its negative effects for most practical applications. Keys that are intended to be used in combinations should be placed in the same row or column of the matrix, whenever possible. Shift keys (Shift, Alt, Ctrl, Window) should not reside in the same row (or column) as any other keys. The SK5100/SK5101 has built-in mechanisms to detect and reject “ghost” keys.

The SK5100/SK5101 provides 6 high current sink pins to drive LEDs directly. The LEDs are CapsLock, Numlock, Scrolllock, Composite, Kana and FN.

USB / PS/2 Interface

The SK5100/SK5101 interfaces to PC via a USB or PS/2 port. The interface is configured by pin 55 USBEN. When the pin USBEN is float, the SK5100/SK5101 is configured to USB interface; when the pin USBEN is tied to ground, the SK5100/SK5101 is configured to PS/2 keyboard interface.

When the SK5100/SK5101 works in USB mode, it follows USB.org’s Universal Serial Bus Specification 2.0 and Device Class Definition for HID 1.11 as a full speed HID composite device. The SK5100/SK5101 has three function endpoints for bootable keyboard, bootable mouse, and consumer and system keys.

When the SK5100/SK5101 works in PS/2 mode, it follows IBM standard PS/2 keyboard protocol to communicate with the host. The SK5100/SK5101 supports keyboard scan code set 1, 2 and 3.

The following standard PS/2 keyboard commands are supported.

Power Management

When the SK5100/SK5101 works in USB mode, it supports selective suspend and remote wake up to get maximum power saving.

When the SK5100/SK5101 works in PS/2 mode, it enters low power mode when no key is pressed and no communication activities happen.

Power On Reset Circuit

The SK5100/SK5101 has build-in low voltage detector.

Oscillator Circuit

The SK5100/SK5101 has build-in oscillator circuit and no external crystal or resonator is needed. The oscillator provides high frequency and 32k low frequency clocks to other blocks.

16-bit Timer

The 16-bit timer provides the timing control for USB or PS/2 communication, keyboard scan and sleep timer wakeup.

Programming Interface

The programming interface is reserved for Sprintek to programming new firmware. PRGCLK and PRGDAT pins are recommended to be connected to a 5 pin header J4 in the schematic. The header needn’t be populated in the final assembly. Three test points for PRGCLK, PRGDAT and XRES are preferred if 5 pin header is not allowed due to space reason.

Backlight Control Circuit

The 8-bit PWM output controls the brightness of backlight circuit. The PWM clock is sourced from 32k clock, the parameters such as period, positive width are programmable.



GPO, SCO, Blackout and Alert LED Control

The SK5100/SK5101 provides 8 general purpose output (GPO) pins that can be associated to any keys. The GPO pins are operated independently. The IC also provides state control output (SCO) logic that can be associated to one key. The SCO controls several GPO together in a predefined table. Blackout is a GPO configured in toggle mode. Alert LED control pin shares pinout with GPO7. All GPO ports can be configured to resistive pullup, resistive pulldown, strong drive and high-Z four modes.

External PS/2 Port

The SK5100/SK5101 provides an external PS/2 port that supports hot plug and hot swap of PS/2 mouse and keyboard devices. If the SK5100/SK5101 is configured to PS/2 interface, then the SK5100/SK5101’s external PS/2 port supports only keyboards. If the SK5100/SK5101 is configured to USB interface, then the SK5100/SK5101’s external PS/2 port supports keyboards, mice including wheel mice.

Flash Data Block

The SK5100/SK5101 provides an on-chip flash data block to store keyboard matrix, GPO and SCO control parameters, backlight control parameters, SKey-scan code mapping table and etc. The flash data block can be edited via FlexMatrix Editor program, uploaded and downloaded via FlexMatrix Programmer program.



KEYBOARD MATRIX DESIGN

Four Keyboard Matrix

The SK5100/SK5101 supports four 8X20 keyboard matrixes for the following cases: Fn off and Numlock off, Fn off and Numlock on, Fn on and Numlock off, and Fn on and Numlock on. The keyboard matrix is stored in on-chip flash memory. The matrix is programmable by FlexMatrix Editor and Programmer software.

Design Keyboard Matrix

Please refer to Microsoft Windows Platform Design Notes “Keyboard Scan Code Specification” to get more information.

Create Keyboard Matrix

The FlexMatrix Editor program enables the user to create keyboard matrix including macro key definition and function key definition, then save them in binary format.

The Editor program allows the user to assign a logical key to any position in the 8 x 20 matrix for each of four situations:

Matrix0 – Num Lock off and Fn off

Matrix1 – Num Lock on and Fn off

Matrix2 – Num Lock off and Fn on

Matrix3 – Num Lock on and Fn on

Fn state is controlled by Fn (function) key in two methods: Level and Toggle. The setting is can be changed via FlexMatrix Programmer.

The Editor program also allows the user to create up to 255 macro keys, which can then be assigned to positions in the matrix.

Once a matrix has been created, it is saved in a binary file. The file can be downloaded to the SK5100/SK5101 flash data block via FlexMatrix Programmer software.

For detailed information and instructions for the FlexMatrix Editor program, see the help file provided with the program.

The Editor program can be downloaded from the SK5100/SK5101 page on the Sprintek web site
